Abstract: A VTEMmax airborne electromagnetic (AEM) survey was successfully completed over King River Resources Epenarra Project (EL 31633/EL 31634) located approximately 135km southeast of Tennant Creek in the Northern Territory. The survey was completed between the 4th-22nd July 2022 with 400m spaced survey lines oriented 090-270 degrees (EL 31633) and 000-180 degrees (EL 31634) for a total of 116 lines and 1462-line km over the project area. The purpose of the survey was to identify conductive units that could be associated with massive sulphide mineralisation, low conductive units, marker horizons within the Georgina Basin, faults, basin geomorphology and other criteria suitable for both IOCG and Stratiform Copper mineralisation. The VTEMmax survey shows that the tenement areas comprise of sporadic conductive cover material overlying more resistive basement. Analysis of the profile data, EM imagery and inversions has generated twenty-six anomalies of interest. Near surface conductive features are more apparent to the east within EL 31633, likely due to recent drainages within the Georgina Basin sediments and controlled by topography. Basin stratigraphic and discrete conductive responses within the project have been delineated. Some are likely due to clays and increased conductivity within the near surface, with some considered to represent targets for further investigation. Significant anomalies associated with basement units have been assigned a high priority with four in EL 31633 and five in EL 31634. These high priority anomalies are situated in significant litho-structural positions. Further modelling and geological interpretation is recommended which may assist to increase target prospectivity before conducting ground investigations. Ground investigation should include gravity and induced polarisation surveys, which will detect dense and polarizable copper sulphide and base metal mineralisation and assist in delineating drill targets.
